 Youngest parts of branchlets minutely puberulous, soon becoming 

 glabrous. Leaves shortly petioled, elliptic-oblong to ovate, apex

 margin entire, 2-3J in. long, 1-lf in. wide, stiffly chartaceous when 

 dry, glabrous, upper surface minutely punctulate, 3-nerved, nerves 

 ju'ominent beneath, cross-veins prominulous ; petiole 3-4 lin. long. 

 Stipules ovate-acuminate, produced below the point of attach-
